4.4.2 Connecting cooling water
This section is relevant for the following:
 For water-cooled devices
Specification Value
Maximum cooling water
pressure
6 bar
Differential pressure
cooling water r p
1 ... 6 bar
Cooling water tem-
perature
approx. 15 °C recommended
10 ... 30 °C permissible (with perform-
ance limitations)
Note the following:
 Fix the cooling water hoses in place with hose clamps.
 Fix the supply hose of the water cooling in place in the sink
area to prevent uncontrolled sliding, also in the event of pres-
sure surges.
Fix the supply hose of the water cooling in place in the sink
area so that spraying out of hot cooling water is not possible.
 Prevent kinking or squeezing of the hoses.
 We recommend using a leak detector with water shut-off to
prevent damage due to cooling water system leaks.
 Ensure that the cooling water meets the required criteria.
 In the case of leaks in the condenser, there is the danger that
refrigerator oil and refrigerant from the refrigerant circuit of the
device can get into the cooling water. Comply with all appli-
cable legal provisions and the requirements of the water supply
companies at the operating site.
